Seo Mun-jo, secretly the Bare Hand Killer. He was given that title as he wouldn’t use any weapons when killing—he only ever used his bare hands. He would choke all his victims until they dropped dead.

This killer was a genius. He had never been caught as he had never left a trace of himself at the murder scenes.

Mun-jo wasn’t lonely though. He had a husband, Yoon Jong-woo. If you had bad blood towards Jong-woo, he would immediately start plotting your death.
